RESQ_SPEC
res_quanLib.RESQ_SPEC : term -> thm -> thm
Specializes the conclusion of a possibly-restricted universally quantified theorem.
When applied to a term u
and a theorem
A |- !x::P. t
, RESQ_SPEC
returns the theorem
A, u IN P |- t[u/x]
. If necessary, variables will be
renamed prior to the specialization to ensure that u
is
free for x
in t
, that is, no variables free in
u
become bound after substitution.
A |- !x::P. t
--------------------- RESQ_SPEC "u"
A, u IN P |- t[u/x]
Additionally, if the input theorem is a standard universal quantification, then RESQ_SPEC behaves like SPEC.
Fails if the theorem’s conclusion is not restricted universally quantified, or if type instantiation fails.
